adding alt attribute to a banner image (opencart) - php

Question

On the website we have banners all over but non of them have any alt text.
Below is the code for, any pointers as to how i can solve this issue? I was thinking maybe having the alt as the image name if possible so need to find a way to echo it.
Any other suggestions? I have 8 banners and don't mind manually adding the alt text for each banner if possible
<?php if ($module_title){ ?>
<div class="box-heading"><?php echo $module_title; ?></div>
<?php } ?>
<div class="box rich_banner grid_holder">
<?php foreach($sections as $section){ ?>
<div class="banner_<?php echo $columns; ?>">
<div class="image zoom_image_container"><img class="zoom_image" alt="" src="<?php echo $section['image']; ?>" />
<?php echo $section['description']; ?>
</div>
</div>
<?php } ?>
</div>
would this be the section of variable below?
<?php
class ControllerExtensionModuleCosyoneBanner extends Controller {
public function index($setting) {
if(empty($setting['module_title'][$this->config->get('config_language_id')])) {
$data['module_title'] = false;
} else if (isset($setting['module_title'][$this->config->get('config_language_id')])) {
$data['module_title'] = html_entity_decode($setting['module_title'][$this->config->get('config_language_id')], ENT_QUOTES, 'UTF-8');
}
$data['columns'] = $setting['columns'];
if (isset($setting['sections'])) {
$data['sections'] = array();
$section_row = 0;
foreach($setting['sections'] as $section) {
$this->load->model('tool/image');
if (isset($section['block'][$this->config->get('config_language_id')])){
$block = html_entity_decode($section['block'][$this->config->get('config_language_id')], ENT_QUOTES, 'UTF-8');
} else {
$block = false;
}
if (isset($section['thumb_image'])){
$image = 'image/' . $section['thumb_image'];
} else {
$image = false;
}
$section_row++;
$data['sections'][] = array(
'index' => $section_row,
'description' => $block,
'image' => $image
);
}
return $this->load->view('extension/module/cosyone_banner', $data);
}
}
}

You are able to use the description in your alt, I think for what's available that is the best solution.
<div class="image zoom_image_container"><img class="zoom_image" alt="<?php echo $section['description']; ?>" src="<?php echo $section['image']; ?>" />
